> O_DIRECT is not a safe way to recover from the journal if you have decided you cannot trust fsync to do its job, because you need fsync to make O_DIRECT write-cache durable.

I was specifically referring not to an fsync in your sense (where the disk or fs does not respect fsync at all so that fsync is a no-op, or where the fs has a bug with O_DIRECT not flushing if it sees nothing dirty in the page cache - by the way I think this is no longer an issue, otherwise it's a kernel bug you can report)

...but to handling an fsync error in the context of the paper from WISC that I linked to in that parent comment, where the kernel's page cache has gone out of sync with the disk after an fsync EIO error ("Fsyncgate"):

"when the page cache can no longer be trusted by the database to be coherent with the disk: https://www.usenix.org/system/files/atc20-rebello.pdf"

The details are all in the paper. Sure, some disks may not respect fsync, but O_DIRECT is still the only way to safely read and recover from the journal when the kernel's page cache is out of sync with the disk (again, details in the paper). It's another fantastic paper out of WISC.
I was just about to say the same. What was striking to me that the managers I’ve met in SF had all been swe:s and worked up the ladder. In my country it’s very rare, most managers have a background in economics and can’t really help the swe:s with anything besides internal politics. The lens they use is that everything is a cost. Even if the system they bought is the problem of why things take time. They also rely heavy on Garter of what is popular.

We are even starting to have them manage doctors!!
Corona is substantially more deadly, and long term effects can be permanent, it’s also in addition to the flu. By your logic we should just let corona run it’s course? You’re willing to let others die just so you can see a concert?

Me neither. That show how good vim/neovim is. I hardly see any issue with vim (and a bunch of plugins) during my daily usage.
The other reason they are popular with gyms (and boat clubs) is twofold; they are virtually indestructible, and whenever do need to replace worn parts, their product support is ace - details manualed, schematics, and parts, even for that forty year old model A.

This support extends right across their lineup - at big regattas, they will be there doing for free oar repairs.

If you want, you can retrofit the latest PM5 monitor on every model, even including the A, and use it on Zwift and friends.

(I have a C2 from '96, and it still goes just like the new one in the gym)

Operating a incredibly limited test program while burning 100s of millions is not my definition of solving general autonomy.

Maybe if they role out this program to city after city in short intervals and have 10000+ taxi operating I would consider it.

Waymo does some things Tesla doesn't do, Tesla does things Waymo doesn't do. Tesla clearly has no interest in offering a money losing taxi service in one small city. Just as Waymo has no interest in doing all the work to figure out the meaning of obscure signs on roads in China.

The question is, when can I click on an app, get a car and drive basically anywhere. That is 'the solution'.

Privacy Conundrums: On Violators and Accomplices
This is really a fight over the definition of "new", isn't it? The transistor was something you can point to. "Decades of incremental process change" isn't, but makes just as big a difference.
Look for any vintage caesium clock made by National, Varian, Hewlett-Packard / Agilent / Symmetricom / Microsemi / Microchip, FEI, FTS / Austron / DATUM, Oscilloquartz, and maybe others. None of them are a restricted item because of a "radio-isotope". Again, cesium 133 is not a radioactive isotope. Atomic timekeeping is based on ultra-precise quantum mechanics, not random nuclear radioactive delay.

Just take your time. Some of us look for months and even years before we find one worth the eBay risk.

There is one fact to consider. I have heard that the 5071A clock is still ITAR classified. It's not because of "atomic" or "cesium", but because the internal design is so advanced that the US decided it was essentially like a military weapon.

If in doubt look for vintage models like 5060, 5061, 5062, or 4050, 4060, 4065 instead of the still current model 5071.
> Computers are just a machine like a 3D printer. You're "physically" moving bytes of data around (that's where most of the heat comes from), doing operations on them, etc. Nowadays you generally can't get them to destroy themselves but in the earlier history you absolutely could tell the machines to tear themselves apart in the same way you can tell a 3D printer to tear itself apart.

This is wrong. It's not what 'unsafe' means for C or C++. You could have 100% safe hardware for your code to run on, and your code could very well still be unsafe. The phrase you're looking for is Undefined Behavior.
Yes, nazis should not be allowed to speak free. And no ramblings about privacy here on HN will ever change my mind.

That's why the left constantly describe anyone who isn't on the left as Nazis, even though they clearly aren't. Free speech requires absolutism - the moment you make an exception of the form, "well ... but not for them" suddenly the term is redefined and huge swathes of people are being dumped in that bucket regardless of reason or evidence.

I'd be happy to sacrifice my own privacy if we can root out the evil of racism, nazism, terrorism, and other things that absolutely everybody agrees are bad.

The people who talk about racism the most are by far the most racist people in society. They manage to be racist whilst claiming to hate racism by redefining it to not be about race, but perceived "power" where "power" is entirely subjective. Hence they can hate on white people whilst claiming to be fighting racism.

Again, the lesson is simple. All free speech must be protected to the absolute end. The moment you make an exception, leftists will en-masse attempt to redefine the word used to delimit the exception to encompass anyone who isn't on their side.

The right isn't above this sort of behaviour either, see the abuse of "terrorist" to mean random people in Afghanistan in the first years of the millenium. But I haven't seen much of that lately. As of 2021 this behaviour is definitely more common on the other side of the hall.

For example, Facebook Prophet (a forecasting procedure, which can in turn be used for anomaly detection) has extensive support for seasonalities and holidays, and would probably work well for the use-case you mentioned.

> You're arguing past the point of the topic. The composition of a receipt for gold on deposit, a gold certificate payable on demand to the bearer can vary widely. The important aspect is that the bearer is paid on demand.

I guess my point was that the coins typically had intrinsic value and nominal value. The intrinsic value usually varied considerably depending on what the coin was made from. So you may end up with two coins with a nominal value of, say, 10 but their intrinsic value varies considerably. People accept the coin at the nominal value because the nominal value is greater than the intrinsic value. They accept the coin at the nominal value because the issuer of it stands behind it. It can be remedied for goods and services, or it is redeemed by paying taxes to the government.

> There's also the phenomenon of coin clipping and shaving. Citing examples of monetary debasement doesn't prove that gold or coins have no intrinsic value. To the contrary, if there was no intrinsic value there would be no need to debase them. Just because someone has 'gotten away with it' doesn't mean it is a valid policy. These events illustrate economic mismanagement.

Oh... I'm not saying coins don't have any intrinsic value - that would be silly. Of course they have intrinsic value. I'm sure if you read my post again then you'll see that's not what I was getting at. Certainly, if the price of precious metal continues to rise then people would clip the coins. If the price of precious metal rises above the nominal value of the coin then people would just take the coins out of circulation entirely because the metal is more valuable than the value the coin was issued at. But I don't think any of this really matters that much. National currencies were debased in the past not because the metal content of the coins diminished but because the solvency of the issuer was brought into question.

> Nor do I accept your premise that price deflation is exclusively harmful. Technological advances, increases in productivity are deflationary. We all benefit from greater productivity. Consumers enjoy lower prices. Artificially suppressing deflation robs consumers of the benefits of increased productivity.

Yes, deflation as a result of technical improvements is clearly a good thing. I was more talking in terms of monetary policy. Eg. linking money supply to a fixed stock of gold, for example, is not a good idea.

> Putting all of that to the side, the argument that deflation must be managed (by a central bank) is an argument for price fixing. This discards the entire premise of decentralized price discovery, in lieu of omnipotent technocracy.

I agree with you. Central banks distort markets, and that's kind of what they are supposed to do in the name of "stability". They can set any interest rate they like. They can print as much money as they like. They can redeem as much money as they like. Clearly the whole point is to manipulate the market of money! Do I think it's a good thing? No. I'd much prefer a world with no central banks!

I am currently reading "Novice Dragoneer" by E. E. Knight and I'm almost finished with it. Next up is the sequel to it, Daughter of the Serpentine.

Fantasy isn't my go to genre but I've been wanting to read something in the fantasy realm because I am just tired of the lawyer/whodunnit stuff.

I am hoping my 12 year old daughter reads it as the heroine is a 14 y/o girl who has to overcome many obstacles and meets them head on.

Another similar use case that is quite common is that your tool can use one of several different calculation kernels. For example there is one option that is fast but closed source, one that is open source but slower and one option that only works with Nvidia GPUs. Most people won't have all three options available, but as long as you have one of them the software works fine.
Right, one guy who isn't even that sure about his own beliefs. I was worried when I read the headline, but the more important thing is that Acton is screening employees to ensure they actually agree with the goals of the organisation. He is clearly able to articulate his own philosophical position on this (focus on bad people, not neutral technologies), and Signal is financially totally dependent on him, which suggests that Signal's philosophy will remain aligned with Acton for the forseeable future.

The primary risk to Signal at the moment seems to come from Google and Apple, not internal employee dissent.
There's no need to be making stupid jokes here at the expense of gay men.
From the POV of an HPC cluster user, when using SLURM's `srun` or similar to schedule a job, this now allows you to use `srun --container=<your container>`, and it will start each node where you app run using the container, and make sure MPI, GPUs, etc, all work.

If you don't know anything about containers, it probably will be a bit hard to imagine what this buys you, but don't worry, as more clusters start moving towards this model, you'll have to learn about containers at some point.

From the POV of the HPC cluster, it means that the `module` system can be replaced with containers, and that can significantly lower the maintenance overhead of the cluster. In a sense, it turns HPC cluster users into HPC cluster maintainers (that have to build their own images, preparing their own environment, etc).

What makes a business stand out from the competition
I'll defend it if you want. I browsed WSB a ton in 2016/2017, while in college. Doubled my initial investment (not much) in a year, and most importantly, learned a ton. I'm still trading now, but don't browse there as much and still have success. I guess maybe I'm one of the lucky ones? I have a friend who browsed the sub back then as well. He bought some of the meme stocks at the time (mostly AMD) and has been holding since. AMD was ~$7 then and is now ~$94.

Yeah, there's a lot of dumb crazy bets on there, and it has become a bit different since options trading started on Robinhood, but it's still a great place to learn things and get investment ideas.

Most of the meme stocks have seemed to perform well (outside of biopharmaceuticals they memed about back then).
Have you tried connected it to something like Kinomap?
I agree with this. It is common to hear "Partial SPARQL 1.1 support"... or "Partial OWL compatibility" or "A variant of SKOS is supported". While it is true that full ECMA6/HTTP2/IPv6/SQL is also rarely provided by implementations, this doesn't hinder their use in productive environments. I think it is rare to reach the parts of ECMAscript that aren't implemented, or the corners of SQL that Postgres/MariaDB don't support. In many of the "Semantic Web Stack", however, one quickly reaches a "not implemented" portion of the 500 page owl standard.

One of the frameworks I use optionally supports a commercial library. If the library is present it enables support, if it isn't it just compiles without it.

This is a nice feature since it avoids a lot of manual configuration. The downside is that support fails silently if the library is missing - since that is the expected case for most users.

Are you sure that has happened?

Do humans dominate insects, fungi, and bacteria?

Do humans dominate the biomass of Earth?

If you limited the scope of your remark to mammals, fish, reptile and birds, I would understand what you are saying. Humans have excelled at habitat destruction. Still, I would point out that the "domination" of which you speak is less than 300 years in duration, with no certainty to last beyond 500 years.

> imho not that hard if you have good abstractions inside the monolith

And that is the big if! The big advantage of micro services is that it forces developers to think hard about the abstractions, and can’t just reach over the boarder breaking them when they are in a hurry. With good engineers in a well functioning organisation, that is of course superfluous, but those preconditions are unfortunately much rarer than they should be.
I see. I knew about those tools at the time, but didn't have much exposure to them as I was a Commodore 64 user, and then moved on to the ST.

> But anything running as your user account can also steal your ssh keys and gain persistence via cron or .bash_profiles or any of a multitude of other methods. How does a writable ADB binary let an attacker do anything more than they could do before?

I have no answers on Linux sadly (but you can disable user-side cron so that you can ensure that cron entries are not editable), but on Windows you can lock down your system by not allowing to run executables from non-whitelisted directories (AppLock), so you can only execute programs from specific directories. Does not really prevent stupidity ("I accidentally run NotAVirus.exe from our build directory") but you frustrate attackers from running their own executable (especially that most drive-by attacks rely on the Download folder or Temporary folder being executable). Of course, you need to monitor your build directories for harmful executables but you significantly reduce the attackers' footprint into the system. Additionally SSH keys can be stored in a format where you need to have an active password in order to decrypt them.

> CURIEs and the depending standards alone are well over 100 pages.

The curie standard is 10 pages long, and those "dependent standards" includes things like RFC 3986 (Uniform Resource Identifiers (URI): Generic Syntax) and RFC 3987 (Internationalized Resource Identifiers (IRI)) - which are well established technologies that most people should be familiar with. And you really don't need to read all of the referenced standards to be able to understand and use CURIE quite proficiently.

> RDF has like 100

Normative specifications of RDF is contained in two documents:

- RDF 1.1 Concepts and Abstract Syntax ( https://www.w3.org/TR/rdf11-concepts/ ) = 20 pages

- RDF 1.1 Semantics ( https://www.w3.org/TR/rdf11-mt/ ) = 29 pages

These page counts includes TOC, reference sections, appendices and large swathes of non-normative content also.

And really the RDF 1.1 primer (https://www.w3.org/TR/rdf11-primer/) should be quite sufficient for most people who want to use it, and that is only 14 pages.

RDF and CURIE is simple as dirt really, maybe too simple, but I think I can explain it quite well to someone with some basic background in IT in about 30 minutes.

And while the other aspects (e.g. SPARQL, OWL) are not that simple, there is inherent complexity they are trying to address that you cannot just ignore. And not everybody needs to know OWL, and SPARQL is really not that complicated either and again most people can become quite proficient with this rather quickly if they understand the basics.

> What we need is a simpler ecosystem, where people can stake their claim on their niche, where they have the ability and power to experiment and explore.

What are the alternatives? Proliferation of JSON schemas which is yet to be ratified as a standard and does not address most of the same problems as Semantic Web Technology? I think there are some validity to your concerns, but semantic web technologies are being used widely in production, maybe not all of them, but to suggest it is not usable is not true.

I have used RDF in Java (rdf4j and jena), Python (rdflib) and JS (rdflib.js) without serious problems.
